No observation (cloudy) 16 Oct. around 1:00 UT NOAA 9192 (snapshots) [Other Regions] We also observed some active regions which were not a target region several times a day. [Events] We observed C2 class flare occurred at * Beijing Astronomical Observatory, Huairou Solar Radio Laboratory. The Solar Radio Spectrometers registered only two small solar radio burst events during the period of 9 Oct to 14 Oct, about 22:30 UT to 9:30 UT each day.
